How to start working out: a free four week plan, what to eat, and when you will actually see it

Starting is the hard part, and almost nobody fails at it because the program was wrong. They fail because the plan was too big, the results were slower than promised, and nothing told them that was normal. This guide gives you a real four week program, the honest timeline for when each change shows up, and the food numbers worked out so you do not have to.

Everything here is free and there is nothing to sign up for to read it. We build a fitness app and we will mention it once at the end, where it belongs.

Key takeaways

• Three full body sessions a week beats five split sessions you will not keep.
• You will feel stronger in two to four weeks. That is your nervous system, not muscle. The visible change is a month or two behind it.
• Aim for one gram of protein per pound of bodyweight. If you weigh 180 pounds, that is 180 grams. The chart below does the arithmetic for you.
• Add a small amount of weight or one rep each week. That single rule is most of what progressive overload means.
• Missing one session costs you almost nothing. Deciding the week is ruined costs you the month.

When will I actually see results?

This is the question that decides whether you are still training in March, so here it is honestly. Four things change, and they change at very different speeds.

The gap between the first bar and the last one is where people quit. You feel stronger almost immediately, you expect the mirror to catch up, and it takes another two months. Knowing that in advance is worth more than any program.

What should the first four weeks look like?

Three sessions a week, on non consecutive days. Monday, Wednesday, Friday is the obvious version. Every session is full body, which means if you miss one you have still trained everything that week.

Do the same four weeks twice if you want. There is no rush to make it harder.

Session A

Movement	Sets and reps	No gym version
Goblet squat	3 sets of 8	Bodyweight squat, 3 sets of 15
Push up (or bench press)	3 sets of 8	Push up on a counter or a wall
Dumbbell row	3 sets of 10 each side	Backpack row, or a towel row on a door frame
Glute bridge	3 sets of 12	Same, no equipment needed
Plank	3 holds of 30 seconds	Same

Session B

Movement	Sets and reps	No gym version
Romanian deadlift	3 sets of 8	Single leg hinge, 3 sets of 10 each side
Overhead press	3 sets of 8	Pike push up, 3 sets of 8
Lat pulldown (or assisted pull up)	3 sets of 10	Doorway or table row
Split squat	3 sets of 10 each side	Same, no equipment needed
Dead bug	3 sets of 10 each side	Same

Session C

Repeat Session A, but add one small thing: either five more pounds on the squat, or one more rep on every set. That is the whole progression rule and you will use it for years.

Week by week: week one, learn the movements and go lighter than feels right. Week two, add a little weight. Week three, add a little more. Week four, keep the weight the same and add one rep per set. Then start again from week one with heavier numbers.

Warm up: five minutes of walking plus one light set of the first movement. That is enough. Elaborate warm ups are a reason to be late, not a reason to be safe.

How much protein do I need, in actual grams?

Protein is the one nutrition thing worth getting right early, because it is the one most beginners get wrong by a lot. The target is one gram per pound of bodyweight a day, which has the nice property of being impossible to forget: if you weigh 180 pounds, eat 180 grams. That is also exactly what BryksBuilt sets your target to, so the number here and the number in the app are the same number.

Research supports anywhere from 0.7 to 1.0 grams per pound for someone training to build muscle, and we aim at the top of that range on purpose. Slightly too much protein costs you nothing. Too little costs you the training. Here is what it means in food terms.

To make 170 grams concrete: that is roughly a large chicken breast, two eggs, a big tub of Greek yoghurt, a scoop of whey and a tin of tuna across a day. It is a lot more than most people eat by accident, and it is the single change that makes the training show up faster. Yes, that is more than one chicken breast. You will live.

Two things nobody tells beginners. Protein timing barely matters, so stop worrying about the thirty minute window. And the drinks are where the calories hide, far more often than the food.

What are the mistakes that make people quit?

1. Starting with five days a week. You will keep it for eleven days. Three is a schedule, five is a mood.
2. Changing the program every fortnight. Progress comes from doing the same movements slightly better, not from novelty. Give anything eight weeks before you judge it.
3. Going too heavy on day one. Your muscles adapt in weeks, your tendons in months. Being sore for four days is not a good session, it is a badly judged one.
4. Eating too little protein and too few calories. Under eating is why people train hard for two months and look identical.
5. Treating one missed session as a failed week. This is the big one. Almost every abandoned fitness plan died on a Wednesday when someone decided the week was already ruined.

What do I actually need to buy?

Almost nothing. Shoes with a flat sole beat running shoes for lifting. A water bottle. That is genuinely it for a month.

You do not need supplements to start. Whey protein is convenient and it is food, not magic. Creatine is the one supplement with a boring, well established track record, and it is cheap, but it is a week five decision, not a week one decision.

How do I keep track of it without it becoming a second job?

Write down what you lifted. That is the minimum, and if you do nothing else, do that, because next week you need to know whether to add weight. A notes app works.

The reason people move to an app is the second part: knowing whether you actually hit your protein number, and having the program adjust when your life does.

That is the thing we built. BryksBuilt logs your lifts and your cardio, logs your food by barcode, photo or voice, and has an AI coach that has seen both, so when you ask why you have stalled it can look at your actual training and your actual eating rather than guessing. It builds meal plans from 522 curated recipes with the macros already worked out, turns them into a grocery list, and there are real coaches inside the app if you decide you want a person. It is free to start, on iPhone and Android.

You can also run this entire guide on paper and it will work. That is the point of giving it away.

Where to go next

If you want to see how the apps in this space compare before you pick one, we ranked nine of them honestly, including the ones that beat us at specific jobs. If you want to know what "AI coach" actually means, we took that phrase apart too.
